If you are comparing with the devel version it may simply be because I
recently disabled the XS versions overrides of _merge_text and
_abort_empty_line because they need significant changes for the source
marks.  I do not think that we should do it, nor that we should take
time to optimize the perl parser, it is only there to ease development,
and even for this purpose it becomes less relevant as times goes by.
